Hi

I want an IC like TPS40211, however , i only need it for  up to 25V, so do you have anything like that?

Vin = 5V

Vout = 12V

SEPIC

basically just a simple  current mode converter.

    The TPS61175 or TPS61500 may be what you need.  Both have integrated FETs and can be configured as SEPICs.  Your output power level will determine whether or not the IC's integrated FET has a high enough current rating.  For a SEPIC, the FET sees the input current and the output current. You can estimate your input current with efficiency = Vout*Iout/(Vin*Iin), solving for Iin with an estimated efficiency (probably around 87%) then add Iin to Iout and see if it is less than those ICs 3A current limit rating.  If not, then I suggest staying with the TPS40211.
